ACCORDION.

SPECIFICATION forming part of Letters Patent No. 223,461, dated January 18, 1880.

- Application filed April 12, 1879.

To all whom it may concern Be it known that I, FERDINAND Zoe-BAUM, of the city, countyand State of New York, have invented certain new and useful Improvements in Aecordions, of which I declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation. Fig. 2 is a plan view ot' the top board removed and turned upside down. Fig. 3 is a cross-section on line y y ot' Figs. 1 and 2. Fig; 4L is a top view of the reed-board as it appears when removed from the top board, and Fig. 5 a cross-section ofthe same on line a' This invention relates to improvements in accordions, and more especially to the construction and mode of attachment ot their reed-boards, and to the means for operating the swell attachment, all ot' which is too particularly hereinafter set forth to need preliminary description.

The top board, A, supports the bridge B and the system of keys O, and is adapted to slide in and out of channels in the upper part, D, ofthe body of the instrument in like manner as is shown and described in Patent No. 192,478, granted to me June 26,1877. The reed-board E is likewise fastened to the under side ot' said top board, so as to be removed with it. ln the present invention this reedboard, instead of being glued directly to the under side of the top board and depending upon such joint alone to afford a wind-tight Connection, is provided with longitudinal strips of packing l, of felt or similar cushioning material, which is let into grooves 2 cut in the inner face ot' said reed-board, which packing, besides affording the means ot" securing a wind-tight joint between the ends ot' the divisions 3 3 of said reed-board, which abut against the under side otl the top board, atfords a packin g-seat for the reeds themselves, as will hereinafter more fully appear. This reed-board is divided, as is usual, into graduated compartments or cells 4, which receive the reeds and form wind-passages. The reeds are inserted in said cells 4L by means of grooves 5 cut in the inner faces of the sides ofthe divisions 3 3, in which they are fitted to slide. The reed-board has its sides inclined, as is 'seen' in Figs. 3 and 5, and the grooves 5 are out parallel with the inclined sides, so that the wind-passages or cells 4 are given a wedge form. The packing-strips or cushions l occupy such aposition that the ends of the reeds 6 will abut against them, thus being' cushioned against the inner face ofthe top board, and thereby provided with a wind-tightjoint at that point, in which position they are securely held by means ot the clamping-strip 7, which is secured over their outer ends by being screwed or otherwise i'astened to the bottom oi" the reed-board. A cushion, 9, ot felt, chamois, or like material, may be interposed between them and the said clamping-strip, as shown in Fig. 3.

By removing the strip 7 the ends ot' all of the reeds will be exposed, and any one may .be conveniently' removed and'replaced when,

from any cause, that operation is desirable.

One row ot' the reeds is in a constantly-operative positionthat is to say, the sides of the reeds composing it are always in condition to admit the passage of air when the position of one or more keys permits the same; but the opposite row is covered, asis usual,by avalve adapted to be moved over the same by means of a controlling device, so as to admit or sluit ott' the ingress otl the air to the second windreeds, and thus produce the swell ett'ect. One branch of the present invention relates'to this swell attachment, and consists in a construction" that embodies a hinged or swinging valve that operates to permit or shut oli" the ingress of the air i'rom the second row ot' reeds, and thus, at will, to render them sounding-reeds. Two t'orms oi" such construction are shown, both of which are wit-hin the scope or" my invention, as will appear from the following description 0l' them A valve, F, oivl suitable shape and proportions to cover one side of the reed-board, and provided with alining of felt or other packing so as to tightly tit against the divisions is suitably hinged so as to be capable ot' swinging from the closed position ot' Fig. 1 to the open position ot' Figs. 2 and 3. The means for controlling the said movements of this valve F may be of various constructions. I have herein illustrated two forms of such means. That shown in Sheet 1 consists of a bell-crank lever, l0, pivoted at 1l to the clamping-strip 7, one end of which bell-crank lever IOO bears against the free edge of said valve F, while the other end ot' said bell-crank lever is attached to rod 12, that is pivoted to a sliding head, 13. This head has a rod, 14, projecting from it through one end ot' the body D, and terminates on the outside by a button, 15, by which a sliding movement may be imparted to it, and thus, through the rod12 and bell-crank 10, canse the said valve to be opened, as in Fig. 3. The reverse movement ot' the bellerank lever permits the valve to be closed by the action of a spring, 16, which was compressed by the openin movement ot said valve. Another form of the means for controlling the movements of this valve, as shown at Fig. 6, consists of an angular arm, 17, projeetinglrom one end of said valve so as to overlie thel sliding head 13, which is there provided with an angular surface, 1S. Then the head 13 is drawn outward its angular surface abuts against the arm 17 and forces said valve outward or open, as seen in Fig. 7, the spring 1U being compressed and acting to close said valve upon the return movement of the head 13,'as before described. The present invention also includes an improved strueture of thekeys. Heretofore keys for aceordions and similar instruments have been constructed of several parts. which` from the nature of the rapid and forcible manipulations ot' said keys, frequently become sepaated and destroyed. This defect was largely overcome by the im1' rovement illustrated in my Patent No. 201,974, dated April 2, 1875; but the key therein shown has one detachable part that is liable to become loose, and thus cause injury to the instrument. The present structure of key has its valve 20, its shank 21, and its ringer-piece 22 composed of one piece ot' metal, that is swaged or bent np into the shape shown in Fig. 8. rjhis construction provides enlarged linger-pieces that protrude through the opening in the bridge and 'form a light and strong key composed ot' a single piece of metal.

What is claimed is- 1. A reed-board for aceordions and similar wiinl-instruments having a packing-strip, 1, laid in recesses 2in the divisions 3 of said base-board, and interposed between the baseboard and the top board, whereby the ends 0f the reeds are seated upon said packing-strip, substantially as described.

2. An accordion the reed-board of which has swinging valve, F, provided at one end with an inclined arm arranged to be operated by a bevel-sided sliding head, 13, substantially as described.

3. A key for accordions whose valve, shank, and {inger-piece are constructed ot' one continuous piece ot' metal swaged into shape, substantially as described.

In testimony whereof I have signed my name to this specification in thepreseneeof two subscribing witnesses.
